Ross; Herbert Dubno [57] ABSTRACT An animal feed and premix concentrate based on inorganic chelates. Metal microingredients including Fe, Zn, Mn, Cu and Co are incorporated in a soluble polymetallic phosphate glass which has an average chain length of 275-5 phosphate atoms and a sodium con tent in gram equivalents equal to 45-90 percent of the total amount of gram equivalent of metallic ion. The concentrate consists of 2-12% Fe; 25-10% Zn; 38% Mn; 0.27% Cu; 0.0l2% Co; 12-27% Na; 22-30% P and 35-55% 0 1 Claim, No Drawings 1 POLYPHOSPHATE GLASS OF POLYMETALS USEFUL 1N ANIMAL FEED The invention refers to a concentrate of microingredients based on inorganic chelates, incorporated in premixes and feed which contains some metals that have the role of microingredients, especially manganese, copper, zinc, cobalt and iron.

A method of including microingredients in premixes: and feeds, in the form of mineral salts, is known. Thei disadvantage of this method consists of the fact that thei ;ions of these metals can escape the intestinal absorption after the ingestion of food. This is possible either; through formation of insoluble compounds, due to the. interaction of these ions with certain components of the food, or through their binding with natural chelating agents (phitic acid, etc) to form complexes of great:

, stability, thus rendering them inactive.

There is also another method of incorporating the microingredients into premixes as chelate-type complexes with organic substances, (organic acids, complex-technological processes and expensive basic materials which increases the fabrication cost. 1

The utilization of different metallic condensed phos-i phates, like pyrophosphate, hexametaphosphate andtripolyphosphate of zinc as microingredient additives in' feeds is also known. The disadvantages of this method} are that the microingredients are introduced in the! .form of low solubility compounds and do not ensure ,the uniform repartition of several microingredients in the mass of a single product.

According to the invention, theconcentrate elimi-. nates the above-mentioned disadvantages since it re- .sults as is desirable, in a soluble product of uniform distribution of its components. The concentrate consists of 212% Fe; 25-10% Zn; 3-8% Mn; 0.2-7% Cu; 0.01-2% Co; 12-27% Na; 22-30% P; and 37-;55% Q i a mixture formed of oxides, carbonates or volatile salts 9f t pest ve me alsw tmicrq n esiba a e:

followed by quenching and grinding of the mixture until it passes through a sieve with meshes of 0.1 mm.

An example of the invention is given below when realizing the incorporation of the microingredients Mn, Cu, and Co in feeds for hybrid breeders and in premixes for hybrid broilers.

A mixture is introduced in a platinum crucible, in the 0 following proportion: 9.61 MnCo ;1.15 CuO; 0.03

CoCl '6H O; 35 Na HP0. 2 H 0 and 54.21 Nal-l PO. H O. The mixture is heated gradually in an electric furnace to the temperature of 9001200C, and maintained for 1-2 hours at this temperature. The

5 melt is poured on a plate of stainless steel and after cooling is ground until it passes through sieve meshes of 0.1 mm, resulting in a violaceous slightly hydroscopic powder having the following composition: 6.27

According to the invention, the concentrate can be obtained by treatmentof a mixture where manganese 'carbofiate is substituted'byT manganese dioxide in an equivalent proportion to ensure the same content of ;l l?fi 35 which at the beginning of the experiment were 35 days old.

in the form of the product obtained in acordance with the invention The following advantages are achieved when the invention is applied:

a greater gain in weight is ensured than in case of the incorporation of microingredients in the form of mineral salts;

the specific feed consumption is reduced as compared to the incorporation of microingredients in the form of mineral salts;

a uniform distribution is obtained for several microingredients in the mass of a single product with a good water-solubility;

easily available natural materials are used as metallic oxides and carbonates from natural storages or industrial wastes and sodium phosphates;

the technique used is simple in comparison with methods required to obtain organo-metallic chelates;

with their increased biocatalytical efficiency.
